When working, the tray does not turn smoothly. There is a frequent noise and the tray, with the weight on top, move and stop continually. That is, it does not turn evenly.

Answer Hello Philip. Check and make sure the shaft W10143947 is not broken in the microwave. If it is good, you will need to replace the motor 815142, based on the information you provided. Hope this helps.
